HQST 3000W Pure Sine Wave Inverter, 12V to 110V, 6000W Surge, LCD Remote — Open-Box, 16% Off

【5s Boost Power – Handles Surge Loads with Ease】Upgraded with 5-second boost capability, this inverter delivers extra surge 6000W to start high-demand appliances like refrigerators, power tools, and pumps. Compared to previous models without boost support, it reduces startup failures and ensures smoother, more reliable operation under heavy loads

【12V to 110V/120V AC - No Sudden Drop-Offs】Delivers 3000W continuous power with 6000W peak, converting 12V DC to stable 110V/120V AC. Especially ideal for sump pump backup during blackouts, helping protect your basement from flooding. Maintains steady output without shutdowns, up to 94% efficiency ensures longer runtime from the same battery

【LCD Remote Control & Multiple Power Outputs】Easily monitor and control power with the remote LCD—no need to access the inverter directly. Features 4 AC outlets, a USB QC 3.0 fast-charging port, and upgraded high-power AC terminals for secure, stable connections when running heavy-duty appliances

【Built-In GFCI Protection – Safer Than Standard Inverters】Unlike ordinary inverters, HQST features built-in GFCI protection to help reduce electric shock risks, especially in wet or outdoor conditions. Includes multiple safety protections against overload, overheating, over/under voltage, and short circuits. Dual cooling fans auto activate under heavy loads or high temperatures for stable performance

【Pure Sine Wave Inverter – Clean, Stable Power】Delivers smooth, grid-like AC power with low THD (3%), far cleaner than modified sine wave inverters (typically 20–40% THD). Runs electronics quieter, cooler, and more efficiently with less noise and vibration, helping protect sensitive devices like TVs, refrigerators, microwaves, CPAP machines, coffee makers, and home audio systems

【Built for HQST Off-Grid Power Systems】Designed for 12V battery bank systems and fully compatible with HQST LiFePO4 batteries, solar panels, and MPPT charge controllers. Ideal for RVs, camper vans, trucks, off-grid cabins, marine applications, home backup, and emergency power during storms or outages
